Insert images into container field in FileMaker using Java

I have to insert an jpeg2000 image into a filemaker container field. I'm using Filemaker 19. googling I found examples like this

INSERT INTO TestDatabase
   (LocatorNum, FileName, SampleSet, PutAs(Image, 'FILE')) VALUES ('003', '003', '003', ?)

But I get a syntax error. I tryed

   INSERT INTO TestDatabase
   (LocatorNum, FileName, SampleSet, Image) VALUES (?, ?, ?, PutAs(?, 'JP2 '))

this is accepted but the result is that the container does not show the image. It shows and internal file named "noname.dat" What is the correct way ? A full example would be great. Thanks
